I have two versionedSchema V1VersionedSchema, V2VersionedSchema. When i create schema with versionedSchema like code below and check version using breakpoint, V1, V2 Schema encodingVersion is same. let v3Schema = Schema(versionedSchema: V1VersionedSchema.self) // encodingVersion: 1.0.0 // schemaEncodingVersion: 1.0.0 let v2Schema = Schema(versionedSchema: V2VersionedSchema.self) // encodingVersion: 1.0.0 // schemaEncodingVersion: 2.0.0 Why encoding version is same? (I think migration plan v1 to v2 isn't work becaus of that)

I have v3 models in coredata (model: Event, Lecture), and make new model in v4 with swiftdata but model name, property is different (model: EventModel, LectureModel). For migration, I add V3Schema, V4Schema and MigrationPlan. enum V4Schema: VersionedSchema { static var models: [any PersistentModel.Type] = [LectureModel.self, EventModel.self ] static var versionIdentifier = Schema.Version(4, 0, 0) } enum V3Schema: VersionedSchema { static var models: [any PersistentModel.Type] = [Event.self, Lecture.self] static var versionIdentifier = Schema.Version(3, 5, 2) } enum ModelMigrationPlan: SchemaMigrationPlan { static var schemas: [any VersionedSchema.Type] = [V3Schema.self, V4Schema.self] static var stages: [MigrationStage] = [migrateV3ToV4] } extension ModelMigrationPlan { static let migrateV3ToV4 = MigrationStage.custom(fromVersion: V3Schema.self, toVersion: V4Schema.self, willMigrate: willMigrate, didMigrate: { _ in Log.debug(message: "Migration Complete") }) } private func willMigrate(context: ModelContext) throws { try migrateLectures(context: context) try migrateEvents(context: context) try context.save() } private func migrateEventTypes(context: ModelContext) throws { // create new v4 event model using v3 event model. } private func migrateLectures(context: ModelContext) throws { // create new v4 lecture model using v3 lecture model. } static let release: ModelContainer = { let v4Schema = Schema(V4Schema.models) let containerURL = FileManager.default.containerURL(forSecurityApplicationGroupIdentifier: "app group id") let databaseURL = containerURL?.appending(path: "**.sqlite") let configuration = ModelConfiguration("**", schema: v4Schema, url: databaseURL!, cloudKitDatabase: .private("**")) #if DEBUG do { try autoreleasepool { let desc = NSPersistentStoreDescription(url: configuration.url) let opts = NSPersistentCloudKitContainerOptions(containerIdentifier: configuration.cloudKitContainerIdentifier!) desc.cloudKitContainerOptions = opts desc.shouldAddStoreAsynchronously = false if let model = NSManagedObjectModel.makeManagedObjectModel(for: V4Schema.models) { let container = NSPersistentCloudKitContainer(name: "**", managedObjectModel: model) container.persistentStoreDescriptions = [desc] container.loadPersistentStores(completionHandler: { _, err in if let err { Log.error(message: "Store open failed: \(err.localizedDescription)") } }) try container.initializeCloudKitSchema() Log.debug(message: "Initialize Cloudkit Schema") if let store = container.persistentStoreCoordinator.persistentStores.first { try container.persistentStoreCoordinator.remove(store) } } } } catch { Log.error(message: "Failed: \(error.localizedDescription)") } #endif return try! ModelContainer(for: v4Schema, migrationPlan: ModelMigrationPlan.self, configurations: configuration) }() But when I run, I got error message.

TabView { SummaryView() .toolbar(.hidden, for: .tabBar, .bottomBar) .tabItem { Text("Title.Summary") } .tag(TabItems.summary) CalendarView() .toolbar(.hidden, for: .tabBar, .bottomBar) .tabItem { Text("Title.Calendar") } .tag(TabItems.calendar) EventTypeView() .toolbar(.hidden, for: .tabBar, .bottomBar) .tabItem { Text("Title.EventType") } .tag(TabItems.group) LectureView() .toolbar(.hidden, for: .tabBar, .bottomBar) .tabItem { Text("Title.Lecture") } .tag(TabItems.lecture) NotificationView() .toolbar(.hidden, for: .tabBar, .bottomBar) .tabItem { Text("Title.Notifications") } .tag(TabItems.notification) } Tabbar is hidden when first opened but tabbar is appeared when I change tab selection. I tested it on iOS 17.1, iOS 17.4, and this bug is only appeared in iOS 17.4.

I use SwiftData, CloudKit, and App Groups. An error occurs on the first run, but it works on the second run. error: CoreData+CloudKit: -[NSCloudKitMirroringDelegate tearDown:]_block_invoke(792): <NSCloudKitMirroringDelegate: 0x12df73750>: Told to tear down with reason: Store Removed error: CoreData+CloudKit: -[NSCloudKitMirroringDelegate _performSetupRequest:]_block_invoke(1192): <NSCloudKitMirroringDelegate: 0x12df73750>: Failed to set up CloudKit integration for store: (null) Error Domain=NSCocoaErrorDomain Code=134060 "" UserInfo={NSLocalizedFailureReason=The mirroring delegate could not initialize because it's store was removed from the coordinator.} I don't know why store path is null in error message. I passed the store url and CloudKit database name in ModelConfiguration. static var release: ModelContainer = { do { let schema = Schema(versionedSchema: ModelSchema.self) let appGroupURL = FileManager.default.containerURL(forSecurityApplicationGroupIdentifier: "group-identifier") let databaseURL = appGroupURL?.appending(path: "Database.sqlite") let databaseName = "Database" let configuration = ModelConfiguration(schema: schema, url: databaseURL!, cloudKitDatabase: .private("iCloud.database.name")) return try ModelContainer(for: schema, migrationPlan: ModelMigrationPlan.self, configurations: [configuration]) } catch { fatalError(error.localizedDescription) } }()

I have 2 vesrion schema and Migration plan. Version 2: Add new properties and Property renamed. static let release: ModelContainer = { do { let schema = Schema(versionedSchema: V2Schema.self) let appGroupURL = FileManager.default.containerURL(forSecurityApplicationGroupIdentifier: "***") let databaseURL = appGroupURL?.appending(path: "Models.sqlite") let databaseName = "Models" let configuration = ModelConfiguration(databaseName, schema: schema, url: databaseURL!, cloudKitDatabase: .automatic) return try ModelContainer(for: schema, migrationPlan: ModelMigrationPlan.self, configurations: [configuration]) } catch { fatalError(error.localizedDescription) } }() enum ModelMigrationPlan: SchemaMigrationPlan { static var schemas: [VersionedSchema.Type] { [V1Schema.self, V2Schema.self] } static var stages: [MigrationStage] { [v1ToV2MigrationStage] } } When I test migration in UnitTest, It works fine. But In running in device, error is occurred. error: Store failed to load. <NSPersistentStoreDescription: 0x1077aa330> (type: SQLite, url: file:///private/var/mobile/Containers/Shared/AppGroup/***/Model.sqlite) with error = Error Domain=NSCocoaErrorDomain Code=134504 "Cannot use staged migration with an unknown model version."

I'm using Music Kit in swiftUI and I try to get duration information from MusicPlayer.queue.currentEntry. But I can't find the solution. How can I get Song duration from MusicPlayer.Queue.currentEntry?
